SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 634,854, dated October10, 1899.

Application filed October 13,1898. Serial No. 693,871. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM FRANCIS MOKEE, a citizen of the UnitedStates, residing at New York, (Brooklyn,) in the county of Kings andState of New York, have invented certain new and useful Improvements inSpringdlinges for Doors, Gates, and Similar Articles, of which thefollowing is a full and complete specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to spring-hinges for doors, gates, and similararticles; and the object thereof is to provide an improved hinge of thisclass whereby the door or gate is kept closed at all times and wherebywhen opened the door or gate will be automatically closed or swung intothe closed position.

The invention consists in the combination, with a hinge of my peculiarconstruction arranged so as to automatically close when the door or gateis opened in either direction by means of two springs, of circularflanged in dependent detachable inclosing caps for each spring, so thatthey may easily be removed for cleaning the spring from accumulateddust, &c., without need of unshipping the entire hinge, as is nowrequired.

The invention is fully disclosed in the fol lowing specification, ofwhich the accompanying drawings form a part, in which- Figure 1 is aside View of a portion of adoor or gate provided with my improved hinge;Fig. 2, a central vertical section of the hinge, and Fig. 3 a transversesection on the line 3 3 of Fig. 1.

In the drawings forming part of this specification the separate parts ofmy improve ment are designated by the same numerals of reference in eachof the views, and in said drawings 1 have shown at 5 a gate-post orsimilar device, or said part may represent a part of the frame of adoor, and I have also shown at 6 a part of a gate or door, and in thepractice of myinvention I provide ahinge which comprises two similarplates 7, which are secured to the gate and to the post 5. One of saidplates 7 is provided with two circular plates 9, which project therefromat right angles thereto, and the other plate 7 is provided with acircular plate 12, which projects at right angles therefrom and which isadapted to enter the space between the circular plates 9, as clearlyshown in the drawings. A bolt or shaft 13 is passed centrally throughsaid circular plates and secured to the central plate 12, and said boltis screwthreaded at one end and provided with a nut 14, and mounted oneach end of said bolt is a circular casing 15, each of which is providedwith an annular flange or rim 16, and said flanges or rims are directedinwardly and form annular chambers, in each of which is mounted a spring1'7. One end of each of said springs is secured to the central bolt orshaft 13, and the opposite end of one of said springs is secured to theadjacent circular plate 9 at 18 adjacent to the plate 7, with which saidplate 9- is connected, and the outer end of the other spring is securedto the other plate 9, adjacent to the outer edge thereof, as shown at19. As thus constructed it will be seen that one of said springs iswound up when the door or gate is swung in one direction and the otherunwound and that this operation is reversed when the gate or door isswung in the opposite direction, and the operation of said'springs, aswill be readily understood, is to hold the gate or door at all times ina closed position and to close the same when swung in either direction.

My improved spring-hinge is simple in construction and operation andperfectly adapted to accomplish the result for which it is intended andis also comparatively inexpensive.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- A hinge consisting of two similar base-plates securedone to a gate or door and one to the post, one of said plates beingprovided with two circular plates projecting at right angles therefromand the other with a single circular plate which fits between the saidcircular plates, a pintle which passes centrally through the plates,springs mounted on the opposite ends of the pintle, the inner ends ofeach spring being secured to the said pintle, and

the outer ends to the first-named circular enee of thesubscribingwitnesses, this 12th plates and an independent detachablecireuclay of September, 1898.

lar fian ed inclosin cap for each sprin held 1 in position by theinintle, all as and 31 the WILLIAM FRANCIS MCKEPJ' 5 purpose set forth.Witnesses:

In testimony that I claim the foregoing as F. A. STEWART,

my invention I have signed my name, in pres- V. M. VOSLER.
